7.6.2 Using a REPL ¶

Another strategy is to open a REPL in an adjacent window and run code in the REPL while having it take effect in the source buffer alongside.

To do this, open an IELM buffer in a window next to a source buffer, and use this snippet in the REPL:

(with-current-buffer (window-buffer (other-window 1))
  (symex-eval
   (symex-traversal
    (maneuver (move forward)
              (move up))))
  (other-window 1))

Here, you can substitute the contents of (symex-traversal ...) with whatever traversal you like.
